Pw.exe is installed onto your computer without your permission and knowledge with the help of trojans. Once the trojan is started, it will install pw.exe and configure it to run automatically when you start an application (files with “exe” extension). This malware also uses this method of running to block the ability to run any programs, including legitimate antivirus and antispyware applications.

When pw.exe is started, it will imitate a system scan. Once finished, this malware will state that your computer is infected with trojans, adware or malware and that you should purchase the full version of the program to remove these infections. Important to know, the malicious program is unable to detect any infections, as will not protect you from possible infection in the future. So, do not trust the scan results, simply ignore them.

While pw.exe is running, it will flood your computer with nag screens, fake security alerts and notifications from your Windows taskbar. A few examples:

Stealth intrusion!
Infection detected in the background. Your computer is now
attacked by spyware and rogue software. Eliminate the
infection safety, perform a security scan and deletion now.

However, all of these alerts, warnings and notifications are fake and like false scan results supposed to scare you into purchasing so-called “full” version of the malicious program. You should ignore all of them!
